A major player in several of the most acclaimed groups of the late 1960s and 1970s, Stephen Stills was a singer, songwriter and guitarist who helped form the backbone of Rock and Roll Hall of Fame inductees Buffalo Springfield and Crosby, Stills & Nash (CSN) while also enjoying a successful career as a solo artist. Steeped in Latin music as a child, Stills brought palpable grit to both groups, as well as some of their greatest hits, including Springfield's "For What It's Worth" and "Suite: Judy Blue Eyes" for Crosby, Stills & Nash. His on-again, off-again relationship with his (CS&N) bandmates, as well as former Springfield member Neil Young, who occasionally joined the supergroup, was the stuff of rock legend during the 1970s due to personality clashes and struggles with substance abuse. But they remained a popular live act well into the new millennium, where they continued to expound the core humanistic values that put them at the forefront of the Woodstock Nation in the late 1960s. Stills' countless contributions to popular music, both with his groups as well as on his own, ensured his status as one of rock's most respected players.
